[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1, referring to Figures 1 to 2 This is the first embodiment of the present utility model. This embodiment provides a door handle, including a sleeve 1 and a pressure rod 2 that is slidably disposed in the sleeve 1. The outer wall of the pressure rod 2 is provided with an abutment block 21. By pushing the pressure rod 2, the pressure rod 2 and the abutment block 21 can slide together on the inner wall of the sleeve 1. The pressure rod 2 and the abutment block 21 are fixedly connected.

[0030] It also includes a spring 3 installed inside the sleeve 1, and a lock head 4 is provided at the end of the pressure rod 2. The two ends of the spring 3 respectively abut against the inner wall of the sleeve 1 and the end of the abutment block 21. The elastic force of the spring 3 can make the abutment block 21 always have the tendency to abut against one end of the sleeve 1.

[0031] The outer wall dimensions of the contact block 21 match the inner wall dimensions of the sleeve 1, and the contact block 21 has a cylindrical structure.

[0032] The pressure rod 2 is installed through the sleeve 1.

[0033] When in use, the door handle is installed on the door. When the door is open, refer to... Figure 2 When spring 3 is in its maximum tension state, the end of the abutment block 21 abuts against the inner wall of sleeve 1. When the door needs to be locked, press the lever 2 to make the abutment block 21 slide on the inner wall of sleeve 1, compressing the spring 3. After the door is closed, turn the lever 22 to make the lock head 4 rotate. The lock head 4 can block the door from opening. At this time, release the lever 2, and the spring force of spring 3 will make the lock head 4 abut against the locking part. At this time, spring 3 is in a semi-compressed state, and the door is locked because of the lock head 4. When opening the door, press the lever 2 to make the lock head 4 lose contact with the locking part, and then turn the lever 22 to make the lock head 4 unobstructed. At this time, the door can be opened normally.

[0034] Specifically, the end of the pressure rod 2 is provided with a pressure handle 22, and the pressure handle 22, the contact block 21, the pressure rod 2, and the lock head 4 are an integrated structure.

[0035] Furthermore, one end of the sleeve 1 is provided with an end cap 11, and the outer wall of the end of the sleeve 1 away from the end cap 11 is provided with a threaded groove 12. The end cap 11 is used to limit the insertion depth of the sleeve 1 when it is installed on the door.

[0036] The outer wall of the threaded groove 12 is threaded with a nut 13.

[0037] Preferably, a gasket 14 is slidably provided on the outer wall of the sleeve 1.

[0038] When installing the sleeve 1 into the lock hole on the door, first insert the sleeve 1 into the lock hole so that the end cap 11 abuts against the door surface, then install the nut 13, and rotate the nut 13 to compress the washer 14. The washer 14 is used to protect the part of the nut 13 that contacts the door and to prevent the nut 13 from loosening, so that the sleeve 1 can be installed on the door.

[0039] In summary, the spring force of spring 3 causes the lock head 4 to fit against the locking part, so that the door has a certain anti-loosening effect after locking. Moreover, opening and closing the door can be achieved simply by pressing and rotating the lever 2, making the operation of opening and closing the door simple.

[0040] Example 2, refer to Figures 1-4 This is the second embodiment of the present utility model. Unlike the previous embodiment, a sliding ring door includes a door handle and a door frame 5. A door body 6 is hinged to the door frame 5. A lock block 7 is provided on the door body 6. The lock block 7 is a locking part used to lock with the lock head 4.

[0041] The lock block 7 is provided with a slot 71, which is used to embed the lock head 4 and engage the lock head 4.

[0042] The door frame 5 is provided with a hinge 51, and the door frame 5 is hinged to the door body 6 through the hinge 51; the inner wall of the door frame 5 is provided with a limiting frame 52, which can limit the position of the door body 6 entering the door frame 5 and increase the sealing and fit between the door body 6 and the door frame 5.

[0043] The rest of the structure is the same as in Example 1.

[0044] Reference Figure 3 , Figure 3 The status of the door handle in the middle is as follows Figure 2As shown, the spring 3 is in its maximum extension state at this time. When the door needs to be closed, press the handle 22 to make the contact block 21 slide on the inner wall of the sleeve 1, compressing the spring 3. Then rotate the door 6 so that the door 6 fits against the limit frame 52. Then rotate the handle 22 again to make the lock head 4 rotate and align with the slot 71. When the slot 71 and the lock head 4 are aligned, release the lever 2. The spring force of the spring 3 makes the lock head 4 lock in the slot 71. At this time, the spring 3 is in a semi-compressed state, completing the closing and locking of the door 6.

[0045] When opening the door, first press the handle 22 to disengage the lock 4 from the slot 71, then rotate the handle 22, and finally rotate the door 6 to open it.

[0046] In summary, this door handle is simple and efficient to operate when opening and closing the door. It also has few parts, good stability, and can avoid the problem of loosening.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
